Return a Vbx object containing the MibLeafīs object identifier and value (a copy of the SnmpSyntax object referenced by MibLeaf::value).
Set the object referenced by MibLeaf::value to the value portion of vb if the value types are compatible and the object identifier of vb and MibLeaf are equal. If MibLeaf::value can be set return SNMP_ERROR_SUCCESS, otherwise an appropriate SNMP++ error code.
Delete the SnmpSyntax object referenced by MibLeaf::value and set the reference to the object referenced by val.
